Little Known Facts About 癌症.

癌症是一组可影响身体任何部位的多种疾病的通称。使用的其它术语为恶性肿瘤和赘生物。癌症的一个决定性特征是异常细胞快速生成，这些细胞超越其通常边界生长并可侵袭身体的临近部位和扩散到其它器官。后者被称为转移。广泛转移是癌症死亡的主要原因。

These nanodrones are created to harness the power of pure killer (NK) cells, which play a crucial function in the body's immune reaction versus tumors. By directing these NK cells specifically towards the web sites of tumors, the nanodrones can efficiently concentrate the immune method's attack on the most cancers cells, likely bringing about far better results for people.[270]

從正常組織到腫瘤組織的形態變化 癌組織在顯微鏡下具有鮮明的外觀，主要是有大量分裂中的細胞、變大的細胞核、細胞大小與形狀改變、失去細胞特化的特徵、失去正常組織結構和細胞間的邊界變的不明顯。免疫組織化學染色法和其他分子生物學標記方法可根據腫瘤細胞的特徵提早發現腫瘤，而有助於診斷和預後。

主要原理是使用高專一性的單株抗體直接結合到腫瘤細胞特有的蛋白質或是細胞激素，影響腫瘤細胞的生長、引起免疫系統反應或是其他功能。已經發展的藥物有針對乳癌的曲妥珠单抗和針對白血病的吉妥单抗在臨床使用。
